MACHINE FOR FO RMING METALLIC EAVES-TROUGHS.

SPECIFICATION forming part of Letters Patent No. 246,736, datedSeptember 6, 1881.

Application filed May 20, 1881. (No model.) Patented in Canada April 13,1881.

To all whom it may concern:

Be it known that I, JAMES DUNN, of the town of Port Hope, in the countyof Durham, in the Province of Ontario, Canada, have invented a new anduseful Machine for Forming Metallic Eaves-Troughs, of which thefollowing is a specification.

The object of the invention is to produce a machine which will enableone man to form eaves-troughing in six-feet lengths; and it consists'ina suitably-formed block hinged to a bed-plate, and provided with springsand adjusting-levers, as hereinafter explained, and operated incombination with a double hinged former provided with suitable handles,and so arranged, in connection with the horizontal block, that metalliceaves troughs can be formed readily by it, as hereinafter explained.

Figure 1 is a perspective view, and Fig. 2 is a sectional end elevation,of my eaves-trough former.

In the drawings, A is a bed-plate; B, the forming-block, which ishinged, as shown, to the bed-plate A by the arms 0.

D is a forming-block, hinged to the bedplate A and provided with ahandle, E. F is also a forming-block, hinged to the block D and providedwith a similar handle, G.

H are spiral springs,'set between the bedplate A and block B, forsupporting the latter.

I are clamping-levers for forcing the block B against its bed-plate Awhen the metallic plate is set in position for forming the eavestrough.

The parts herein described may be made of wood or other suitablematerial, and are connected together, substantially as represented, in astrong manner, so as to be able to resist the strain caused by theforming of the trough.

- In order to form the trough the plate is first placed in the receiversJ, situated along the face of the block 13, as represented. Thesereceivers support the plate, so that when the blocks D and F are broughtup against it the outside edge of the eaves-trough is first formed, theblocks D and F are then allowed to fall back, and the edge of the platethus turned up is slipped in below the block B, butting against theadjusting-plates K, situated on the bed-plate A, as represented, thelevers I being removed from the block B, so as to permit it to be forcedaway from the bed-plate A by the action of the spiral springs H. When inthis position the metal plate can be slipped in below the block B, itsbent edge, as I have before said, butting against the adjusting-platesK, which are slotted and provided with clamping-screws. When themetallic plate is thus situated the levers l are turned on their pivots,so that their upper endsyi i, acting on the inclined surfaces, at (a, ofthe block B, will force said block down upon the bed-plate, so as togripe the metal plate between it and the bedplate. The forming-block Dis then drawn up, forcing the plate against the block B, the faces ofthe two blocks being shaped to the desired form of the eaves-trough, andthis movement forces the projecting spring-receivers J into recessesmade to receive them in the block B. In this way the body of theeaves-trough is formed, when, by pushing over the formingblock F, theshape of the eaves-trough is completed. The forming-blocks D and F maythen be allowed to fall back and the levers I removedfrom the block B,which will then spring open and permit the withdrawal of the platebeneath it, which is by that time formed into the shape of theeaves-trough.

It will be seen that in a machine constructed as shown and described theformation of the metal plate will be both rapidly and easily effected,requiring only the service of one man, and as the plate is formed intoshape by the same formers at each operation the different lengths of theeaves-troughs thus made can be depended upon to be the same shape, andwill, therefore, be rapidly put together.

I may mention that the forming-blocks can be changed and smaller orlarger ones substituted, permitting the formation of dilferent sizes ofeaves-troughin g.

What I claim as my invention isl. A bed-plate, A, provided withadjustable gages, and having hinged to it a formingblock, B, providedwith suitable clamping devices, and a forming-block, D, furnished with ahandle, E, in combination with a formingblock, F, hinged to the block Dand having a handle, G, the said parts being arranged to operate asdescribed, for the purpose ofmaking metallic eaves-troughing, asspecified.

2. In a machine for making metallic eavestroughing, a forming-block, B,provided with spiral springs H, and clamping-levers I, arreceivers J incombination with the hinged ranged and operating in combination with the10 blocks D and F and bed-plate A, for the purforming-blocks D and F,substantially as and pose of forming the edge of the eaves-trough, forthe purpose specified.

5 as specified. JAMES DUNN.
